Surgical Treatment for Patients with Coronary Heart Disease and Ventricular Aneurysm
Bibliographic record
Abstract
Objective To summarize clinical characteristics and treatment results of adult patients with coronary heart disease and ventricular aneurysm,and evaluate surgical outcomes.Methods Clinical data of 86 adult patients with coronary heart disease and ventricular aneurysm who underwent surgical treatment in Fu Wai Hospital from January 2011 to November 2012 were retrospectively analyzed.There were 70 male and 16 female patients with their average age of 57.7±10.6 years and average body weight of 71.7±10.5 kg.Preoperative echocardiography or left ventriculography showed left ventricular thrombus in 22 patients.Coronary angiography showed 47 patients with 3 vessel disease,29 patients with 2 vessel disease,and 10 patients with single vessel disease.Sixteen patients underwent direct linear suturing of the aneurysm off pump,39 patients underwent simple linear suturing under cardiopulmonary bypass,15 patients received endoventricular purse-string reconstruction,and 16 patients received endoventricular purse-string reconstruction and patch plasty.Three patients underwent reexploration for bleeding.Sixty-four patients received concomitant coronary artery bypass grafting(CABG).Results Postoperatively 2 patients(2.3%)died of refractory ventricular fibrillation and multiple organ dysfunction syndrome respectively.Patients undergoing concomitant CABG received 2.3±1.2 grafts on the average.Seventy-eight patients(92.9%)were followed up for 2-24 months after discharge.During follow-up,patients’ angina symptoms significantly resolved,heart function improved in varying degrees,and no new sign of myocardial ischemia was found on electrocardiogram.Left ventricular ejection fraction(LVEF)was significantly higher than preoperative LVEF(51%±7% vs.41%±9%,t= 6.20,P=0.00),and left ventricular end-diastolic diameter(LVEDD)was significantly smaller than preoperative LVEDD (54.2±6.2 mm vs.56.0±6.8 mm,t=4.60,P=0.00).Conclusion Ventricular aneurysm repair and concomitant CABG(or ventricular septal perforation repair,mitral valvuloplasty et al)are positive and effective treatment strategies for postinfarction ventricular aneurysm.Satisfactory clinical outcomes can be achieved by individualized treatment based on appropriate surgical strategies according to the size of ventricular aneurysm.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
